It is a figure which shows the amount of displacement.

[Specimen]
The test body is a steel folded plate test piece (left and right width 2000 mm × front and back depth 1700 mm) wound on a steel frame assuming a purlin (span 1450 mm) through a tight frame, using a support member and a rail member. This is a greening system in which four greening trays (front and rear two rows) are placed and fixed (see FIGS. 1 and 2).
The supporting member is fixed by a method of sandwiching the gouge joint portion of the crest of the existing folded plate, and a rail member (presser foot) is fixed to the supporting member with a fixing bolt. The greening tray is supported by two sides orthogonal to the flow direction of the folded plate of the rail member (presser foot).
Accordingly, the wind pressure received by the tray is transmitted in the order of the rail member (holding metal), the support member, the folded plate, the tight frame, and the purlin. Since the support members are arranged at every corner of the tray (1000 mm interval in the left-right direction), the support member bears a part of the wind pressure applied to the four adjacent trays at the maximum. In this test, four trays were installed and attention was paid to the strength of the support member at the intersection.

[Test method]
As shown in FIG. 16, the test was performed by inverting the top and bottom of the specimen and applying a load corresponding to the lifting force due to wind pressure by suspending sand bags from the tray. Two round bars (diameter 20 mm × 150 mm) were installed on the back of the tray so that the load was divided into four equal parts. FIG. 17 shows the load loading step during the test. The displacement amount of each part of the test specimen was measured using a displacement meter (sensitivity: 1/50 mm, non-linearity: 0.2% FS) installed at the position shown in FIG.

[Test results]
Details of the test results are shown in FIGS.
The relative displacement between the rail member (presser foot) and the steel folded plate increased as the load increased to a load of −2.00 kN / m ² (see FIG. 22), and thereafter the displacement increased rapidly, but the load of load-3 also greening system in time .53kN / ^{m 2} was not destroyed.
As an example of calculation of design wind load (standard wind load for exterior materials), a value of −1880 N / m ² is calculated, and the greening system according to the present invention is robust despite having a simple configuration. It was confirmed to have a structure (wind pressure resistance).

In this example, the following experiment was performed on the culture soil filled in the greening tray. A greening tray having the same configuration as in Example 1 was used.

[Experimental Example 1]
Peat moss 28% (% is volume%, the same applies hereinafter), pearlite 4%, organic compost 45%, pure sand soil 20%, and organic magcalin were mixed in a small amount to obtain culture soil P.
When the weight was measured, it was about 4.5 kg weight / 12 liter.
The culture soil P was filled in a tray for greening, and 1000 trays (about 250 m ² ) prepared by planting small seedlings of Sedum (Mexican mannengusa) were cultivated on a farm in Hyogo Prefecture for 6 months.
There was no particular problem with the growth of Sedum, and after 6 months, the training was completed.

[Experiment 2]
Culture soil Q was obtained by mixing a small amount of 35% peat moss, 2% vermiculite, 7% perlite, 40% organic compost, 11% pure sand, and shell fossils, organic magcalin, long fertilizer, and charcoal.
When the weight of the culture soil Q was measured, it was about 3.9 kg weight / 12 liters.
Similarly, culture soil Q is filled in a greening tray and 1000 seedlings (about 250 m ² ) planted with seedlings of Sedum (Mexican munengusa) are prepared and cultivated for 6 months under the same conditions as culture soil X. did.
In this case as well, there was no particular problem with the growth of Sedum, and after 6 months, the breeding was completed.

[Experiment 3]
Peat moss 60%, vermiculite 4%, perlite 13%, organic compost 9%, pure sand 9%, and shell fossils, organic magcalin, long fertilizer, and charcoal were mixed in a small amount to obtain culture soil R.
When the weight of the culture soil R was measured, it was about 2.9 kg weight / 12 liter.
Similarly, culture soil R is filled in a greening tray and 1000 seedlings (about 250 m ² ) planted with seedlings of Sedum (Mexican munengusa) are prepared and cultivated for 6 months under the same conditions as culture soil P. did.
In this case, the growth of the sedum was considerably inferior to that using the culture soils P and Q. This is thought to be mainly due to a considerable decrease in soil water retention.
As a result of continuing cultivation after 6 months of cultivation in an incomplete state, it took one year from the start of the experiment to become a finished product.

The culture soils P, Q, and R in the above experimental examples are all configured to be lighter than conventional culture soils, assuming that they are used for greening the folded plate roof.
Although the culture soil R became the lightest, it took a long time to cultivate and grow greening plants. The cultured soils P and Q are not particularly problematic in terms of the growth of greening plants. In particular, the cultured soil Q is about 15% lighter than the cultured soil P and can be suitably used in the greening system according to the present invention. .
